IMPROVEMENT Ill GAS-GENERATOR.

dbitlzehule nitriet in in fliet-Eaters atntt mit uiting am tf its time.l

Be it known that I, MATTHEW FLOON, of the town of Bloomington, in thecounty of McLean, and State of Illinois, have invented a new andimproved Gas-Generator and syringe; and I do hereby declare that thefollowing is a fallend exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, making part of this specification.

The nature oimy invention consists in the combination of agas-generatorand syringe of peculiar and novel construction, for thepurpose of applying remedial agents to diierent parte of the human bodywhich have hitherto been impossible to reach by means ordinarilyemployed.

`My invention is peculiarly adapted to the treatment of diseases of thewomb, to which remedial agents can be applied directly to the parta'ected, whether in the interior or exterior of that organ, andimmediate relief' obtained, which, without the aid or employment of myinvention, could not be so eeetually reached.

To enable others skilled in the ais-ft to make andluse my invention, Iwill proceed todescribe its construction and' operation.

Figure I is a side elevation of the dexible syringe, showiughow thedifferent nozzles may be applied.

Figure II is a side elevation of the guage'nei-atar.l Y

Figures III and IV represent nozzles of dierent forms employed fordifferent purposes, they being attached to the syringe. i

Letters of liko name and kind indicate like parts iu each of thetigures.

A represents a ilexible bag or'eack, that may be made of rubber, or anyother suitable material, provided with a mouth-piece, upon which is ascrew-thread, for the purpose of attaching diercnt forms of nozzles,adapted for the treatment 'of diierent diseases located in diicrentparts oi' the body, and for the use and application ci',

different remedial agents. B represents a gasgenerator, made of hardrubber, or other suitable material, coustructed cylindrical in form, asshown in Fig. II. The fountain C is madeof hard rubber, or soft flexiblerubber, or other suitable material, and is connected or applied to thegenerator B by tube d. Said tube is provided with a stop-cock, c, so asto cut oii communication between the water-fountain e and gasggencratorB, or may be used without stop-cock if with flexible rubber. Drepresents a nozzle, employed for introducing remedies to the mouth of'the womb and exterior of that organ. F rcpresenis anozzle for thepurpose of injecting the necessary remedies into the neck of the womb,which pass readily in the interior of thatporgan also may bel npplied toother organs of the body inlike manner. It will be observed that anyform of nozzle may be attached to the syringe by means of thescrew-thread. p u

Any ei'ervescing compound, as supercarbonate of soda two parts, andtartaric acid one part, may bc used for the purpose of producing gas,when water is introduced from thereservoir C, and the medicinalagent,.if in asolid form, may be mixed with the soda and acid, or, if ina liquid form, it should be mixed with the water in the reservoir. Inthis Way nitrate of silver, belladona, morphine, &c.',' may beintroduced into'the cavities of ,the body in a form which will insuretheir contact with every portion of the interior surface, and wi'th aneffect superior to any mode of application hitherto in use. l

The operation ot' this instrument is simple. The proper medicinal agentis placed in` the generator, and the `sack A, rolled together so as toexpel the air, is then attached by screwing its neck into the top of thegenerator, and the cock F opened. The fountainC having been llcd withwater the cock c isopened, and thc-water permitted to iiow into thegenerator, and the cock e is then closed again to prevent the passage ofgas into the fountain or reservoir C. YThe contact of water withthe'vmedicinal agent employed causes a chemical transformation, by whichthe desired medicated gasis liberated, and, rising,'lls the sack A,which, when containing the desired quantity, is shut oli` by turning thecock'F, and it may ,then -bo removed from the generator. The propernozzleis attached tothe neck of the sack A, and by introducing the sameinto the cavity of the body, where the medicinal gas is to be applied,the gas is expelled by pressure upon the sack. In this way medicated gasmay be produced and conveyed to any distance for use.

Having thus described my invention, what I `claim as new, and desire tosecure by Letters Patent of the United States, is I A The combination ofthe fountain G, connected to the generator B by means of the tube-d,with the sack A provided for different forms of nozzles, subistantiallyas herein shown and described and for the purposes set forth.
